LEAD SIGHT FOR, FIREARMS.

Application filed August 15, 1925. Serial No. 50,386.

My present invention has for its object to provide lead sights'forfirearms, and to this end it consists of the novel devices andcoinbinations of devices hereinafter described and defined in the claim.

As is well known, it is very difficult for the average hunter, andparticularly the novice, to accurately gauge the proper lead or distancethat one must shoot ahead of moving objects or flying game birds inorder to hit the same. In one form of the invention, re-' movable frontand rear lead sights are provided and each sight includes, the former apair of beads and the latter a pair of sight openings through which saidbeads may be seen. Said pairs of beads and sight openings arehorizontally and transversely spaced in respect to the barrel of afirearm and located equidistant from the axis of said barrel. The beadson the front lead sight are located a greater distance from the axis ofthe barrelpoint on the projected axis of the barrel of said fire arm.Said focal point being on the projected axis of the barrel of the firearm, is at the intersection of lines extending through the beads andsight openings on opposite sides of the barrel of the fire arm, andwhich focal point may be located by the hunter moving his head eitherback or forth along the projected axis of the barrel of the fire arm.

The invention further provides for the use of a pair of horizontally andtransversely spaced beads on the front lead sight on each side of theaxis of the barrel of the firearm, for use in near and far shooting.Said invention further provides a front lead sight having beads that maybe horizontally adj listed tow rd and from the axis of the bar rel ofthe firearm. The invention also provides lead sights having attachingmeans for detachably securing the same to a firearm, and which sights,after a hunter has learned to accurately gauge the proper lead, may beremoved from the barrel of the firearm.

In the accompanying drawings, which illustrate the invention, likecharacters inclicate like parts throughout the several views.

Referring to the drawings:

Fig. 1 is a side elevation of a single barrel shot gun having a pair ofthe front and rear lead sights applied thereto;

Fig. 2 is a plan view of the same;

Fig. 3 is a view looking into the muzzle of the gun barrel and at thefront lead sight, on an enlarged scale;

Fig. 4 is a plan view of the parts shown in Fig. 3;

Fig. 5 is an elevation of the rear lead sight removed from the gun;

Fig. 6 is a fragmentary detail view in elevation, showing a modificationof the front lead sight;

Fig. 7 is a plan view of the same;

Fig. 8 is a view corresponding to Fig. 3, but showing a modification ofthe front lead sight;

Fig. 9 is a side elevation of said modification; and

Fig. 10 is a fragmentary plan view of the modification.

Referring first to Figs. 1 to 7, inclusive, there is illustrated asingle barrel shot gun, and of the parts thereof it is important to notethe breech 8, barrel 9, and front sight or bead 10.

As previously stated, the preferred form of the invention provides afront lead sight 11 and a read lead sight 12. Said front lead sight 11comprises a horizontal bar 13 having at its longitudinal center a clampcomprising a pair of depending segmental spring jaws 14 adapted to besprung around the barrel 9 for detachably securing said bar transverselythereto. In the center of the bar 13 is a hole 15 through which the bead10 projects and thereby properly positions the front lead sight 11 onthe barrel 9 and holds the same against turning or axil movements onsaid barrel.

Cutand pressed from the bar 13 is a pair of upstanding inner beads 16and a pair of upstanding outer beads 17, and the beads of each pair arelocated on opposite sides of the barrel 9, equi-distant from the axisthereof.

By reference to Fig. 4, it will be noted that the beads 10, 16 and 17are all on the same line, and which line extends transi 'ersely of thebarrel 9 at right angles to the axis thereof.

The rear lead sight 12 comprises a short transverse bar 18 having aclamp in the form of a pair of spring jaws 19 at the ends of said barand adapted to yieldingly engage the sides of the breech 8 anddetachably secure said sight thereto. A pair of horizontal and laterallyspaced sight openings 20 is formed in the rear sight 12 by folding thebar 18 at its end portions to form pairs of late ally spaced upstandinglugs 21. As shown, each lead sight 11 and 12 is formed from a singlepiece of spring steel, but, of course, may be made from any suitablematerial and in any desired shape.

To take aim at a moving object or a flying game bird, the hunter mayfirst sight along the barrel 9, using the bead 10, in the customarymanner, and then swing the muzzle of said barrel until one of the beads16 or 17. (depending on the distance the shot is to be made. and on theside of the barrel t) in which the same being swung), may be seenthrough the sight opening 20 on the same side of the barrel 9. In takingthe last noted aim, the hunter simply moves his head either forward orbackward along the projected axis of the barrel 9 to find the focal.point, so as to bring one of the beads 16 or 17 into alignment with oneof the sight openings 20. Some hunters may prefer to take a direct sightsimply by using the lead sights and not the gun sight.

Referring now to the modification shown in Figs. (5 and 7, thehorizontal bar 22 of a front lead sight 23 is provided on each side ofits longitudinal center with a pair of laterally spaced beads 24, (onlyone side being shown), having depending stems 25 which project throughlongitudinal slots 26 in said bar. On the lower ends of the stems 25 arethumb nuts 27, by which the beads 2i may be clamped onto the bar 22 indifferent adjustments toward and from the axis of a gun barrel.

Referring now to the modification illus trated in Figs. 8, 9 and 10, thehorizontal transverse bar 28 comprises two duplicate sections having attheir abutting ends depending segmental clamping figures 29 adapted tosnugly fit around a gun barrel Ill). These members of the bar 28 areconneeted and held clamped on the gun barrel Flt) by a C-shaped spring31 loosely oncircling the clamping lingers 2!) with only their endsengaging the same at the members of the bar 28. The end portions of hespring 31 are bifurcated to receive reinforcing webs 32 between themembers of the bar 28 and the clamping fingers 29. By thus bifurcatingthe end portions of the spring 31, the same is held interlocked with thelead sight and keeps the members thereof assembled. The abutting ends ofthe members of the bar 28 have formed therein half seats 33 arranged toreceive the front sight 34: on the gun barrel 30 and thereby sccurelyhold the lead sight against axial or circumferential movement on the gunbarrel 30. llpstanding inner and outer pairs of beads 35 and 36 aresecured to the members of the bar 26. It will be noted that the pairs ofseats 16, ll', 35 and 36 are located materially outward of the sides ofthe gun barrels in order to give the proper lead.

To remove the lead sight shown in Fig. 8 from the gun barrel 30, it isonly necessary to draw the outer end of the bar 28 downward to separatethe inner ends thereof and release the half seats 33 from the sight 3%,and then move said lead sight axially from the outer end of its gunbarrel 30.

The words beads and sight openings are used in a broad sense to coverany kind of sight guides.

The above described front and rear lead sights may be very easily andquickly ap' plied to a firearm or removed therefrom, and they areextremely simple and of comparatively small cost to manufacture. Ifdesired, a hunter may use only the front lead sight and dispense withthe rear lead sight.

What I claim is:

A lead sight for firearms comprising a flat straight horizontal bar, theend portions of which are folded inward under the intermediate portionof said bar and terminate in spaced reversely formed areuatespring--jaws applicable to grip -the barrel of a. tirearlifis ai d banhaving a gun sight. aperture niidway between said jaws, and a pair ofsighting beads on said bar located one on each side of said aperturerespectively.

In testimony whereof I aiiix my signature.
